Alienware M17X R2 memory upgrade

This 8 GB kit contains two 4 GB DDR3 SO-DIMM modules built for the Alienware M17X R2 notebook. Each stick uses a 204-pin interface and runs at 1333 MHz with CL7 timing. The unbuffered, non-ECC design suits the platform's two memory sockets.

Sustained load behaviour

Rated at 1.5 V with 7-7-7 timings, the modules maintain their specified frequency during extended sessions. Major-brand chipsets and 2Rx8 organisation help deliver stable throughput without throttling. The kit lacks a heat spreader, so chassis airflow determines peak temperature.

DDR3 SO-DIMM limits

The notebook accepts a maximum of 8 GB across its two slots, so this kit fills the platform entirely. A 64-bit operating system is required to address the full capacity. Builders needing more memory or a different form factor must choose another platform.

Questions about this item

How much power does the 1.5V DDR3 kit draw when the Alienware M17X R2 runs all day?

Each module operates at 1.5V, the standard voltage for DDR3 SODIMM, so total power draw stays within the notebook's original memory power budget.

What must the Alienware M17X R2 already have for this 204-pin kit to work?

The notebook needs two free 204-pin SODIMM slots and a 64-bit operating system to address the full 8GB capacity.

Will the CL7 1333MHz modules run with any original memory I keep in the Alienware M17X R2?

The system will clock all installed memory to the slowest module's speed and tightest common timings, so mixing with slower DDR3 SODIMM is supported.
